Bit Eight Zero Stuffing. A means of encoding 8 bit data via leased line [generally T-1] so all-8 bits in each transmission frame can be used to carry data.
Bipolar eight zero substitution; a line coding scheme to substitute 000 + - 0 - + for 00000000 if the preceding pulse was +, and 000 - + 0 + - for 00000000 if the preceding pulse was -. Done to maintain ones density
Bipolar with eight zero substitution. Clear channel line coding option on DS-1 service allows the DS-1 user to obtain greater throughput and functionality from their DS-1 facilities. The use of B8ZS allows users to transmit data at a rate of 64 Kbps per DS-0, achieving what is referred to as a clear channel. Applied against all 24 DS-Os on a DS-1, the effective data throughput of the DS-1 facility is increased with B8ZS from 1.344 Mbps to 1.536 Mbps, a 14% increase in throughput. CSUs with B8ZS support are required on both ends of the user's circuit.
Refers to Bipolar 8 Zero Substitution.
A T1 line coding scheme, also known as Clear Channel, that operates at 64Kbps by sending a string of eight zeros with a deliberate bipolar violation which maintains line synchronization. Bandwidth: The relative range of frequencies that can be passed by a transmission medium without distortion. The greater the bandwidth, the greater the information-carrying capability of the transmission medium. Bandwidth, which is measured in Hertz, may also be expressed as the number of bits that can be transmitted per second.
Bipolar with 8 Zeros Substitution. A method for 1's density control for bipolar transmission signals such as T1. See also D4.
inary ero ubstitution, a technique used to maintain required ones density in T1 communications.
(n.) Bipolar with eight zero substitution, a line code used for T1 which converts any string of 8 zeros of a DS-1 signal into a code which at the far end is converted back to eight zeros. The coding actually inserts BPVs that are realized at the next multiplexer point and that taken out of the signal.
a technique used to satisfy the ones density requirements of digital T-carrier facilities in the public network while allowing 64 Kbps clear channel data. Strings of eight consecutive zeroes are replaced by an eight-bit code representing two intentional bipolar pulse code violations (000V10V1).
Binary with 8 Zero Substitution. Line code type, used on T1 and E1 circuits, in which a special code is substituted whenever eight consecutive zeros are sent over the link. Code is then interpreted at the remote end of the connection.
Binary 8-zero Substitution. A line-code type, used on T1 circuits, that substitutes a special code whenever 8 consecutive zeros are sent over the link. This code is then interpreted at the remote end of the connection. This technique guarantees ones density independent of the data stream. Sometimes called bipolar 8-zero substitution.
Modified AMI code in which eight consecutive binary 0's are replaced with one of the following bit strings: "000+-0-+" if the preceding pulse was positive, "000-+0+-" if the preceding pulse was negative.
Binary 8-zero Substitution. Basic bipolar coding algorithm for digital telephony. At the transmitting end, a string of 8 zeros is deliberately replaced with a pulse that produces a bipolar violation. At the receiving end, bipolar violations are replaced with a string of 8 zeros.
inary Eight () ero uppression. A T1 line encoding. Suitable for videoconferencing transmission lines.
Binary Eight Zero Suppression. An encoding scheme for transmitting data bits over T1 transmission systems.
Binary 8 Zero Substitution. It is a technique that allows 64Kbps clear data per T-carrier channel. Because of the ones density requirement of a T-carrier system, a one must be inserted for every seven consecutive zeros. B8ZS circumvents this requirement by inserting two code violations on a physical link instead.

Binary 8 Zero Suppression. An alternate line coding parameter (setting) option to AMI, with relation to editing of T1 and WAN router software services.
Abbreviation for bipolar with eight-zero substitution. A T-carrier line code in which bipolar violations are deliberately inserted if user data contains a string of 8 or more consecutive zeros. Note 1: B8ZS is used to ensure a sufficient number of transitions to maintain system synchronization when the user data stream contains an insufficient number of “ones” to do so. Note 2: B8ZS is used in the European hierarchy at the T1 rate.
